Avariable speed reciprocating compressor of mass 400 kg has a natural frequency of 16.2 hz. (a) design an optimum auxiliary mass damper, so that the maximum dynamic magnification for the compressor is limited to 4.0. determine the optimum damping required. (b) what is the dynamic magnification of the compressor if the absorber is optimally damped, but tuned ot the natural frequency of the system? assume same mass ratio as in part (a).
